Clutch Slipping on Vulcan 1500

Before you tear your engine apart and start changing plates and putting in heavy duty springs, try this simple little fix that worked for me.
Open the Clutch master cylinder and look in the bottom and you will see (2) holes. One of the holes will look like it has a tiny ball valve in it. Take a small stiff piece of wire (bread tie with plastic removed) and stick it in this ball valve to clear any debris. What happens is that the fluid cannot return from the clutch to the cylinder and keeps some pressure in the line thus the slipping clutch. If that valve is clogged, you can put as many new clutches or heavy duty springs as you want and the clutch will still slip. Take it from someone who just changed all the parts then still had to flush the hydraulic cylinder, clean that hole out, add new DOT 4 fluid, bleed clutch and now it works GREAT!
